Abstract
To address the problem of low flux density generated by superconducting magnets and the onerous cooling system in existing superconducting magneto-hydrodynamic (MHD) thrusters, which leads to overall low thrust efficiency of MHD thrusters, a capacitive deionization based conductivity enhancement system is designed, and the performance of the conductivity enhancement system is quantitatively analyzed to provide a new technical direction for the conductivity control of the spiral channel. In addition, the relationship between the performance index of the thruster and the conductivity was investigated. The results showed that the conductivity, electromagnetic force, thruster, and electromagnetic efficiency were increased by 54%, 54.5%, 56.8%, and 19%, respectively, when the ion concentration in the spiral channel reached 1.38 mol L−1 during the ion release phase of the porous electrode. The adsorption concentration of the porous electrode increased with increasing loading voltage and porous electrode thickness and decreased with increasing inlet velocity.
